As we can see from the picture, a massive number of eggs is laid by a fully grown frog. And then eggs hatch into embryos and each of them become a tadpole which have no legs. After a period of time growing up, their front legs begin to emerge more clearly day by day. It is the end of first steps to be a adult frogs.

Next, their hind limbs start to appear obviously and tadpole frogs start to learn how to step ashore by their front legs which are quite robust. Thenceforth their tails shorten before disappear completely and that is the moment that they are mature. Finally, adults frogs cross and spawn to start the life of frogs of the next generation.

As we can see in picture,  cacao trees are grown in several countries such as American, Africa and Indonesia. After an amount of time, when the pods in the trees are red and ripe, they are picked. And then people take the white cacao beans inside beans to prepare for the next steps. Next, beans are fermented to have taste as desired before being exposed to the sun to by dry. After that they put it into many large sacklothes. Jute bags of beans are transported by the train or the larry and taken to the factory. The following steps is that they grill beans in a high temperature before crushing it. After being crushed, the outer shells are removed. Finally, the inner parts are pressed to be used to produce chocolate.
